Изобретение относится к арматуростроению и может быть использовано на газовых магистральных трубопроводах, тепловых электростанциях, в химической промышленности и т.д. для быстрого (аварийного) перекрытия магистрали. Клапан содержит корпус, в котором установлен диск с седлом и уплотнительными элементами, расположенными по контуру двух проходных окон. В корпусе размещена захлопка, выполненная из двух створок-секторов, каждая из которых соответственно через кривошип связана со своим приводным валиком. В приосевой зоне клапана установлен обтекатель с окнами, в которых располагаются створки захлопки при открытом клапане. Приводные валики снабжены рычагами, смещенных относительно друг друга. Рычаги соединены через штанги с планкой, связанной с пружинным приводом. Механизм привода клапана содержит ходовой винт, на котором размещена каретка с кулачками захвата, взаимодействующими с планкой. Положением кулачков управляет электромагнит с бойком. Ходовой винт приводится в движение приводом. 5 ил.The invention relates to valves and can be used on gas pipelines, thermal power plants, in the chemical industry, etc. for fast (emergency) overlap of the highway. The valve includes a housing in which a disk with a saddle and sealing elements located along the contour of two windows is installed. In the housing there is a flap, made of two leaf-sectors, each of which, respectively, is connected with its drive roller through a crank. In the paraxial zone of the valve, there is a fairing with windows in which flaps are located with the valve open. The drive rollers are equipped with levers that are offset relative to each other. The levers are connected via rods with a strap connected to a spring drive. The valve drive mechanism includes a lead screw on which a carriage with gripping jaws interacting with a bar is placed. The position of the cams is controlled by an electromagnet briskly. The lead screw is driven by a drive. 5 il.
